I have 35 years of experience, and specialize in the field of optics with specific knowledge in the areas of lasers, imaging and optical fibers. I have published on such topics as medical imaging, nonlinear optics and optical fibers and microscopy. I have testified on photolithography, imaging and optical resolution. I especially enjoy the detective work required in intellectual property cases. I’ve been teaching undergraduates and graduate students for many years, and I can present and explain complicated subjects clearly and simply.
